Applications
This tungsten electrode is widely used in industrial projection and spot welding processes, particularly in:
Automotive parts and electronic components manufacturing
Battery terminal and connector welding
Precision metal joining and electrical contact welding
High-frequency or high-current resistance welding equipment
Welding of special alloys and high-strength materials
Structural component fabrication requiring dimensional accuracy and durability
Projection Welding Process
Projection welding is a variant of spot welding where welding occurs at embossments (projections) on one or both parts to be joined. Heat generation is similar to spot welding but concentrated in the projection area.
Process Advantages
Allows closer weld spacing
Projections enable precise positioning
Ideal for welding screws, nuts, and fasteners to metal sheets
Concentrated welding current provides higher energy efficiency
Electrode Requirements
Pure tungsten electrodes are particularly suitable for projection welding applications. Their high hardness and lower electrical conductivity (compared to copper electrodes) enable them to withstand high welding pressures while maintaining stable welding performance.

Frequently Asked Questions (FAQ)
1. Why choose pure tungsten electrodes for projection welding instead of copper-based electrodes?
Pure tungsten electrodes offer superior hardness and high-temperature resistance (melting point 3,410°C), lasting 5-10 times longer than copper electrodes while withstanding the extreme pressures of projection welding.
2. What is the expected service life of your tungsten electrodes?
Our electrodes typically perform 50,000-100,000+ welds before replacement, depending on welding parameters and materials.
3. Can you customize electrode dimensions for our specific application?
Yes, we fully customize all dimensions and specifications based on your technical drawings and welding requirements.
4. How do I maintain the tungsten electrodes?
Regularly clean electrode surfaces, control welding parameters within recommended ranges, and ensure adequate cooling for optimal performance.
5. What materials can be welded using pure tungsten electrodes?
Our electrodes are suitable for steel, stainless steel, aluminum alloys, copper, brass, galvanized materials, and various thicknesses from 0.5mm to 10mm+.
